UNITED STATES PATENT OFFICE.

W. I. CANTELO, OF PHILADELPHIA, PENNSYLVANIA. ASSIGNOR TO STUART &PETERSON, OF SAME PLACE.

STOVE.

Specification of Letters Patent No. 28,035, dated April 24., 1860.

To all whom it may concern:

Be it known that I, W. I. CAN'rnLo, of the city of Philadelphia, Stateof Pennsylvania, have invented a new, useful, and Improved Gas-BurningStove or Heater; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

My invention relates to that class of stoves or heaters in whichordinary coal or other gas, is used as a fuel, and my invention consistsof a box or chamber to which both air and gas are freely admitted incombination with a cap, the latter having curved or inclined ridgesprovided with slits in the manner described hereafter, so that theexternal air may have a free access to the lower part of the flameproduced by the ignited gas as the latter passes through the slits,thereby increasing the heat of the flame and rendering the stove orheater applicable to culinary and other purposes.

In order to enable others to make and use my invention I will nowproceed to describe its construction and operation.

On reference to the accompanying drawing which forms a part of thisspecification, Figure 1, is an exterior View of my improved gas burningstove or heater. Fig. 2, a vertical section of the same, and Fig. 3, aground plan.

Similar letters refer to similar parts throughout the several views.

My improved gas burning stove consists of a hollow stand A, and a cap B,attached to the top of the said stand by any suitable appliances, thewhole forming a chamber to which the exterior air has free accessthrough any convenient number of openings a a, and to which the gas isadmitted through a pipe C, terminating in a tip 0, which is situatedcentrally, or thereabout, with the chamber formed by the stand and itscap. The latter has an annular projection I) having inclined sides, andoutside this annular projection is another similar projection (Z, theannular continuity of which may or may not be interrupted at twoportions of its circumference, that is, between the points m and 3 Fig.3, according to the use to which my improved stove or heater may beapplied.

The annular projection Z has at its summit a narrow annular slit 6communicating with the chamber formed by the stand A and its cap B; andthe annular, or partially annular projections (Z have similar narrowslits communicating with the same chamber.

At different points on the cap B are projections f 7", for receiving theobject to be heated, the locality and number of these projectionsdepending upon the form and size of the object, their upper surfaceshowever must be above the surface of the projections in which are theabove mentioned slits.

The gas and air being simultaneously admitted into the chamber willescape through the slits in the projections Z) and cl, at which pointthe gas, which has become thoroughly and intimately intermixed with theair, is ignited.

It will be observed that the flame is bounded on each side by two ridgesforming the sides of the projections in which the slits for the escapeof the gas are formed. These ridges afford an opportunity for theexternal air to pass in the direction of the arrows, Fig. 2, toward theflame, supplying the same with that amount of oxygen which causes it toassume a clear blue color, a certain indication of an intense heat,which could not be attained by allowing the gas to pass through slitsformed in a level cap without the above described ridges.

It will be readily seen that the same result may be obtained by formingthe projections of the cap with curved instead of inclined sides so thatthe air may be directed to the flame in the manner described.

. It will also be seen that my improved gas burning stove or heater maybe made of a variety of forms differing from that illustrated, that theslotted projections may be straight instead of annular, that they may beso situated that the flame shall be horizontal instead of vertical, andthat the number and extent of the slotted projections may be regulatedby the use to which my improved gas burning stove or heater may beapplied,

and to the extent of the surface to Which it has to communicate heat.

\Vithout confining myself therefore to the provided with slits in themanner and for 10 the purpose herein specified.

In testimony whereof, I have signed my precise form and arrangement ofparts name to this specification in the presence of 5 herein described,

I claim as my invention and desire to secure by Letters Patent.

The combination of the chamber and cap the latter having inclined orcurved ridges two subscribing Witnesses.
